Similar studies of the prevalence of S. hemolyticus as determined by throat cultures in early cases of influenza are shown in Table VI.
The only point of interest in these observations is the increased prevalence of S. hemolyticus in cases examined late in the epidemic of influenza as compared with that found early in the epidemic. The significance of this will be discussed in other parts of this report.

The results obtained in normal individuals have, therefore, been tabulated in groups dependent upon the culture method employed. These groups have been subdivided according to the time and the place of the study, such explanatory notes as seem necessary being added. (See Tables VII-IX.)
